The Environment One grinder
pump is a well-engineered,
reliable and proven product;
proper installation will assure
years of trouble-free service.
The following instructions
define the recommended
procedure for installing
the grinder pump station.
These instructions cover the
installation of units with and
without accessways.
This is a sewage handling
pump and must be vented in
accordance with local plumbing
codes. This pump is not to be
installed in locations classified
as hazardous in accordance
with National Electric Code,
ANSI / NFPA 70. All piping and
electrical systems must be in
compliance with applicable
local and state codes.
1. REMOVE PACKING
MATERIAL: The User
Instructions must be given to
the homeowner. Hardware
supplied with the unit, if any,
will be used at installation.
2. TANK INSTALLATION:
Lift the station using only the
methods described on page 9,
Lifting Instructions. The tank
is supplied with a standard
grommet for connecting the
4” DWV (4.50” outside dia.)
incoming sewer drain. Other
inlet types and sizes are
optional (Caution: 4” DR-35
pipe has a smaller diameter
and won’t create a watertight
joint with the standard
grommet). Please confirm
that you have the correct
inlet before continuing. If a
concrete ballast is attached to
the tank, lift only by the lifting
eyes (rebar) embedded in the
concrete. Do not drop, roll, or
lay tank on its side. This will
damage the unit and void the
warranty.
4
• If the tank has no
accessway (Fig. 1b): (Indoor
Installation): The pump
may be installed on or in the
basement floor (see Fig. 1b).
If the tank is to be set on the
floor, it must be a flat and level
bearing surface. If the tank is
to go into the basement floor,
it must be anchored to prevent
unit from floating due to high
ground water (see Chart 1,
page 12 for weight).
• If the tank is to go in the
floor: A hole of the correct
width and depth should be
excavated. The tank must be
placed on a 6” bed of gravel
made up of naturally rounded
aggregate, clean and free
flowing, with particle size not
less than 1/8” or more than 3/4”
in diameter. The wetwell should
be leveled and filled with water
prior to pouring the concrete to
prevent the tank from shifting.
If it is necessary to pour the
concrete to a level above the
inlet, the inlet must be sleeved
with an 8” tube before pouring.
There must be a minimum
clearance of three feet directly
above the tank to allow for
removal of the pump.
• If the tank has an
accessway (Fig. 1a):
Excavate a hole to a depth,
so that the removable cover
extends above the finished
grade line. The grade should
slope away from the unit. The
diameter of the hole must be
large enough to allow for a
concrete anchor. Place the unit
on a bed of gravel, naturally
rounded aggregate, clean and
Figure 2a
120 VOLT DUPLEX WIRING
free flowing, with particles not
less than 1/8” or more than
3/4” in diameter. The concrete
anchor is not optional. (See
Chart 1 on page 12 for specific
requirements for your unit.)
The unit should be leveled
and the wetwell filled with water
to the bottom of the inlet to help
prevent the unit from shifting
while the concrete is being
poured. The concrete must be
vibrated to ensure there are no
voids.
If it is necessary to pour the
concrete to a higher level then
the inlet, the inlet must be
sleeved with an 8” tube before
pouring.
If your unit is a model taller
than 93” it may be shipped in
two sections, requiring field
assembly. See Field Joint
Assembly Instructions on page
8 for additional information.
3. INLET PIPE
INSTALLATION: Mark the inlet
pipe 3-1/2” from the end to
be inserted. Inlet pipe should
be chamfered and lubricated
with a soap solution. Lubricate
the inlet grommet with soap
solution as well. Insert the pipe
into the grommet up to the
3-1/2” mark. Inspect to ensure
the grommet has remained
intact and in place.
4. DISCHARGE: The use
of 1-1/4” PVC pressure pipe
Schedule 40 and polyethylene
pipe SDR 11 or SIDR 7 are
recommended. If polyethylene
is chosen, use compression
type fittings to provide a
smooth inner passage. It
is recommended that a
Figure 2b
240 VOLT DUPLEX WIRING
Redundant Check Valve
Assembly (E/One part no.
NC0042GXX) be installed
between the pump discharge
and the street main on all
installations. Never use a ball
type valve as a check valve.
E/One recommends the
valve be installed as close
to the public right-of-way as
possible. Check local codes for
applicable requirements.
CAUTION: Redundant check
valves on station laterals
and anti-siphon/check valve
assemblies on grinder pump
cores should not be used as
system isolation valves during
line tests.
• If the tank has no
accessway: (Indoor
Installation) The discharge
connection is a 1-1/4” male
NPT. The discharge piping
must incorporate a shut-off
valve and a union with a
minimum pressure rating of
160 psi, or a suitable piping
disconnect to allow for removal
of the pump core. The valve
should be of the type that
provides a full-ported passage
(i.e. a ball or gate valve). A
standard 1-1/4” union or a compression type coupling should
be used as a disconnect joint.
• If the tank has an
accessway: There is a ball
valve and a quick disconnect
pre-installed in the accessway.
There is a 1-1/4” female NPT
discharge connection on the
outside of the tank 41” above
the bottom of the tank.
5. BACKFILL
REQUIREMENTS: Proper
backfill is essential to the
long term reliability of any
underground structure.
Several methods of backfill are
available to produce favorable
results with different native soil
5
conditions.
The recommended method
of backfilling is to surround
the unit to grade using Class
I or Class II backfill material
as defined in ASTM 2321.
Class 1A and Class 1B are
recommended where frost
heave is a concern; Class
1B is a better choice when
the native soil is sand or if a
high, fluctuating water table
is expected. Class I, angular
crushed stone, offers an added
benefit in that it needs minimal
compaction. Class II, naturally
rounded stone, may require
more compactive effort, or
tamping, to achieve the proper
density.
If the native soil condition
consists of clean, compactible
soil with less than 12% fines,
free of ice, rocks, roots, and
organic material, it may be
an acceptable backfill. Such
soil must be compacted in
lifts not to exceed one foot to
reach a final Proctor Density
between 85% and 90%. Noncompactible clays and silts are
not suitable backfill for this
or any underground structure
such as inlet or discharge
lines. If you are unsure of
the consistency of the native
soil, it is recommended that a
geotechnical evaluation of the
material be obtained before
specifying backfill.
Another option is the use of
a flowable fill (i.e., low slump
concrete). This is particularly
attractive when installing
grinder pump stations in
augured holes where tight
clearances make it difficult to
assure proper backfilling and
compaction with dry materials.
Flowable fills should not be
dropped with more than 4
feet between the discharge
6
nozzle and the bottom of the
hole because this can cause
separation of the constituent
materials.
6. VENTING: The unit must
be properly vented to assure
correct operation of the pump.
If you have an indoor unit, it
can be vented through the
2” port supplied at the top of
the wetwell or through the
incoming sewer line with a 2”
pipe (the vent must be within
4 feet of the grinder pump,
and before the first change of
direction fitting).
The outdoor units are
supplied with a vent pipe from
the wetwell to the top of the
accessway. Failure to properly
vent the tank will result in faulty
operation and will void the
warranty.
7. ELECTRICAL
CONNECTION: (Supply panel
to E/One Alarm Panel)
Before proceeding, verify that
the service voltage is the same
as the motor voltage shown
on the name plate. An alarm
device is to be installed in a
conspicuous location where
it can be readily seen by the
homeowner. An alarm device is
required on every installation.
There shall be no exceptions.
Wiring of supply panel and
alarm panel shall be per
Figures 2a and 2b, alarm panel
wiring diagrams and local
codes. A dedicated 30 amp
breaker is required before a
240V duplex alarm panel, and
a dedicated 40 amp breaker is
required before a 120V duplex
alarm panel.
8. ELECTRICAL
CONNECTION: (Pump to
Panel) (Fig. 4) The grinder
pump station is provided
with a cable for connection
between the station and the
alarm panel (supply cable).
The supply cable is shipped
inside the station with a small
portion fed through the cable
connector mounted on the
wall of the fiberglass shroud.
The supply cable, a six
conductor tray cable, meets
Figure 3
TYPICAL IN-GROUND
SECTION VIEW
NEC requirements for direct
burial as long as a minimum of
24” burial depth is maintained.
Those portions of the cable
which have less than 24” of
cover must be contained in
suitable conduit. This includes
the vertical portion dropping
to a 24” depth at the station
and the length rising out of the
ground at the control panel.
NOTE: Wiring must be installed
per national and local codes.
Conduit must enter panel from
bottom and be sealed per NEC
section 300.5 & 300.7.
8a. Installing E/One supply
cable:
1) Open the lid of the
station. Locate the cable and
the feed-thru connector on
the wall of the shroud. If the
station has a field joint and
was delivered in two pieces,
be sure both halves of the
EQD are securely assembled
together. Loosen the nut on
the connector and pull the
supply cable out through
the connector until it hits the
crimped-on stop feature on the
cable, approximately 24” from
the EQD. **IMPORTANT: All
but 24” of the cable must be
pulled out of the station, and
the EQD and Equalizer should
be hung as high in the station
as possible to ensure that the
pump functions properly. Do
not leave the excess cable in
the station.
2) Retighten the nut. This
connection must be tight or
ground water will enter the
station.
3) Feed the wire through the
length of conduit (contractor
provided), which will protect it
until it is below the 24” burial
depth.
4) Position the conduit
vertically below the cable
connector along side of the
station reaching down into the
burial depth. Attach the small
guard (protective shroud)
provided with the station to
protect the exposed cable
where it enters the station.
Four self-tapping screws are
Figure 4
Power at the station must not drop below 10% of nameplate
voltage. Maximum Recommended Length:
120 Volt 60’ (min. voltage at pump — 108V)
240 Volt 150’ (min. voltage at pump — 216V)
Consult factory for longer lengths
TYPICAL SUPPLY CABLE
CONFIGURATION
provided.
5) Run the cable underground, in a trench or tunnel,
to the location of the alarm
panel. Leave a 6- to 12-inch
loop of cable at each end to
allow for shifting and settling.
Connections made at the panel
are shown in Figures 2a and
2b.
9. DEBRIS REMOVAL: Prior
to start-up test procedure, the
core must be removed and the
incoming sewer line flushed to
force all miscellaneous debris
into the tank. Next, all liquid
and debris must be removed.
Once tank is clean, reinstall
the pump and proceed with the
test.
10. TEST PROCEDURE:
When the system is complete
and ready for use, the following
steps should be taken to verify
proper pump and high level
alarm operation:
a) Make sure that the
discharge shutoff valve is fully
open. This valve must not
be closed when the pump is
operating. In some installations
there may be a valve, or
valves, at the street main that
must also be open.
(Ignore all Trouble
indications, LEDs and/or
messages until the panel
is reset at the end of this
procedure.)
For model DH152:
b) Turn on the alarm breaker.
c) Fill tank with water until the
high level alarm turns on. Shut
off water.
d) Turn on pump breaker;
the pump should turn on
immediately. Verify that the
high level alarm turns off
and then the pump turns off.
Proceed to Step E.
For model DR152:
b) Fill tank with 100 gallons of
7
water.
c) Turn on pump and alarm
breakers; the pump and high
level alarm should turn on
immediately.
d) Verify that the high level
alarm turns off and then the
pump turns off.
e) Clear/Reset the alarm
panel:
Sentry and T260 panels:
Reset is not required.
Protect Panel: Turn pump
and alarm breakers off and
back on simultaneously.
Protect Plus Panels: Perform
a “cold start” from the Initialize
System menu. Any user setting
that were previously chosen
will not be reset.
f) If any Trouble or alarm
conditions are indicated after
the panel is reset, contact your
local service provider.

Field Joint Assembly Instructions
IT IS EXTREMELY IMPORTANT THAT THE JOINT IS SEALED PROPERLY BEFORE
BACKFILLING. EXCAVATING A UNIT FOR REPAIR IS VERY EXPENSIVE AND CAN BE EASILY
AVOIDED BY USING PROPER CAUTION DURING THE FOLLOWING PROCEDURE.
Parts included in Field Joint Kit:
Identify all parts before proceeding
with installation.
(16) 3/8-16 x 1-1/2 long screws
(16) 3/8-16 Elastic Stop Nuts
(32) Flat Washers
(1) Length Sealant (Sika) Tape
(1) Hole Punch
(1) Vent Pipe Extension
1) Carefully clean and dry both
accessway flanges with solvent.
IMPORTANT: Sealing surfaces
must be dry to ensure the
sealant adheres correctly.
2) Starting at one hole of tank
flange, apply two layers of Sika
Tape around the inside half of the
flange. Align the outside edge of
the tape with the bolt circle. Move
to the adjacent hole and apply
one layer of Sika Tape around
the outside of the flange. Align
inside of tape with the bolt circle.
Remove the backing paper as you
lay the adhesive on the flange.
Do not stretch Sika tape during
application; it may result in a
leak. The tape should overlap at
the end by approximately 1/2 inch,
as shown in Fig. 5a. If a section
of Sika Tape is misapplied, the
bad section may be cut out and
replaced. Cut away the poorly laid
portion cleanly with a knife and be
sure to over lap the tape at each
end about 1/2 inch.
3) Using the tool provided,
punch a hole through the tape at
each of the 16 existing bolt holes
in the flange. Be careful to keep
the exposed sealant clean and
dry.
4) Insert three of the sixteen 3/816 x 1-1/2” long bolts, with a flat
washer, into the flange attached to
the upper part of the accessway.
These will act as guides while
aligning the bolt pattern of the two
flanges.
5) Support the upper accessway
section a few inches over the
tank, making sure to align the vent
port in the lid with the vent pipe
in the tank. Once aligned, lower
the upper section onto the mating
flange using the three bolts to
guide it to the proper position. See
Fig. 5b.
6) Insert the remaining 13 bolts
with flat washers into the flanges.
Place a flat washer and elastic
stop nut on the end of each bolt,
turning the nut on just enough to
hold the washer in place.
7) Tighten the bolts until the
sealant begins to squeeze out
from between the flanges. To
ensure a consistent, sturdy seal,
tighten them in the following
sequence: 1, 9; 5, 13; 3, 11; 7, 15;
2, 10; 4, 12; 6, 14; 8, 16. Always
be sure to tighten one bolt and
then the bolt at the position 180°
from it; see Fig. 1 for position
Figure 5a
numbers.
8) Using the same sequence as
in Step 7, tighten each bolt to 60
in-lbs. Visually inspect the joint,
each bolt and each nut should
have a flat washer between it and
the flange, and a uniform amount
of sealant should be protruding
from the seam along the entire
perimeter.
In the event that there are
any voids in the sealant, the
joint may leak. Take corrective
actions if necessary and be
sure that the joint is leak free
before continuing.
9) Install the vent pipe extension
piece, which was shipped inside
the upper piece of the accessway.
Push the extension pipe into
the bell mouth fitting on the pipe
installed in the wet well tank. Be
sure the pipe is seated correctly.
Slide the top end of the extension
pipe into the receptacle on the
bottom of the lid.

Lifting Instructions
FAILURE TO FOLLOW THESE INSTRUCTIONS COMPLETELY WILL VOID WARRANTY.
* Transporting unit to installation site: Always lift a unit from the bottom for the purpose of
transportation. The station should be received attached to a pallet for this purpose. Never roll a station
or move it on its side.
1. No Ballast, No Eye bolts
(Ballast to be poured in place):
If the concrete anchor is to be
poured while the station is in place
and it has no eye bolts, lift the
unit by securing two 20 foot flat
or round eye slings around the
station. Loop the slings around
the station and use an appropriate
lifting beam or tie-down strap to
ensure the safety of the station
and people close to the unit. (see
below)
10
2. No Ballast, Factory- Installed
Eye Bolts (Ballast to be poured
in place): If the concrete anchor
is to be poured while the station
is in place lift the unit by securing
straps to the eyebolts supplied on
the lower flange, as shown below.
Keep station oriented vertically to
avoid any damage. Only lift from
the eyebolts to put unit in hole,
not for moving any distance. (see
below)
3. Precast Ballast: Never lift a
station that has a ballast attached
by any means except the rebar
hooks. The weight of the concrete
will damage the station if you
attempt to lift it from any part of
the station. (see below)
E/One Grinder Pump Station Ballast Calculations
Any buried vessel that is submerged, or partially submerged, in water will be acted on by an upward
buoyant force that attempts to return the vessel to a non-submerged state. The magnitude of this
buoyant force is equal to the volume of the vessel that is submerged multiplied by the density of water.
On most in-ground installations a ballast, or concrete anchor, of proper volume and weight is required
to resist the buoyant force. The amount of ballast required for a given set of installation site conditions
may be calculated as follows.
Installation Site Assumptions
1. Low water table – under worst case ground water or flood conditions only the wet well portions of the E/One grinder pump stations will be submerged.
2. Backfill materials are per these installation instructions.
3. The consulting engineer should perform a soil test to determine if the assumptions that have been made are valid. If the site conditions differ from these assumptions, then the consulting engineer must revise the calculations as shown in this document.
Physical Constants
1. Density of Water = 62.4 lb/cu ft
2. Density of Concrete = 150 lb/cu ft (in air)
3. Density of Concrete = 87.6 lb/cu ft (in water)
4. Density of Dry Compacted Backfill = 110 lb/cu ft
5. Density of Saturated Backfill = 70 lb/cu ft
Procedure
A. Determine The Buoyant Force Exerted On The Station
1. Determine the buoyant force that acts on the grinder pump station when the wet well is submerged in water.
2. Subtract the weight of the station from the buoyant force due to the submerged wet well to determine the net buoyant force acting on the station.
B. Determine The Ballast Force Exerted On The Station
1. Determine the ballast force applied to the station from the concrete, saturated soil and dry soil
C. Subtract The Ballast Force From the Buoyant Force.
1. Note – if the installation site conditions are different from those listed above, the consulting engineer should recalculate the concrete ballast.
Ballast Calculations
The following calculations are to outline the areas used to determine the volumes of the different
materials for the ballast. All sections referred to in the calculations are marked on the accompanying
drawing.
11
E/One Grinder Pump Station Ballast Calculations
Sample Calculation
Volume of Station Wet Well = 22.0 cu ft
Station Weight = 470 lb
Station Height = 93.5”
A. Buoyant Force
1. The buoyant force acting on the submerged DH152-93 is equal to the weight of the displaced water for the section of the tank that is submerged (wet well).
Fbuoyant = (density of water)(volume of DH152-93 wet well)
= (62.4 lb/cu. ft)(22.0 cu. ft)
= 1372.8 lb
2. The net buoyant force acting on the station (Fnet-buoyant) is equal to the buoyant force (Fbuoyant) minus the weight of the grinder pump station.
Fnet-buoyant= 1372.8 lb – 470 lb
= 902.8 lb
B. Ballast Force
1. Determine the volume of concrete (if applicable) & soil (saturated and dry)
Section I: Used To Determine The Volume Of Concrete
Area = (Height)(Width) + (Triangular Area)
= (20”)(3.1”) + (1/2)(7”)(5.5”)
= 81.3in2
Volume= (Area)(Average Perimeter of the cylinder)
= (81.3in2)(2π)(20.95”)
= (10695.2 in3 )(1/1728 ft3/in3)
= 6.1 ft3
Section II: Used To Determine The Volume Of Saturated Soil
Area = (Height)(Width)
= (16.5”)(3.1”)
= 51.2in2
Volume = (Area)(Average Perimeter of the cylinder)
= (51.2in2)(2π)(21.0”)
= (6755.7 in3 )(1/1728 ft3/in3)
= 3.9 ft3
12
E/One Grinder Pump Station Ballast Calculations
Sample Calculation, Continued
Section III: Used To Determine The Volume Of Dry Soil
Area =(Height)(Width) + (Top Area)
= (36.5”)(3.1”) + (17.5”)(9.3”)
= 275.9in2
Volume = (Area)(Average Perimeter of the cylinder)
= (275.9in2)(2π)(17.9”)
= (31030.2 in3 )(1/1728 ft3/in3)
= 18.0 ft3
2. Determine the combined ballast
Ballast (total) = Ballast (concrete) + Ballast (saturated soil) + Ballast (dry soil)
= (Vconcrete)(density concrete in water) + (Vsoil)(density wet soil) + (Vsoil)(density dry soil)
= (6.1 cu ft)(87.6 lb/ft3) + (3.9 cu ft)(70 lb/ft3) + (18.0 cu ft)(110 lb/ft3)
= 534.4 lb + 273 lb + 1980 lb
= 2787.4 lb
C. Subtract the buoyant force from the ballast force to determine the final condition
Final Condition
= Ballast Force - Buoyant Force
= 2787.4 lb – 902.8 lb
= 1884.6 lb
The approach outlined above may be used to calculate the ballast requirements listed below.

Adjusting the Height of the Grinder Pump Station
TO INCREASE STATION HEIGHT 6 INCHES
1. Increasing station height can be done without cutting the station. Use the E/One Extender cover shroud
kit (ND0082G01) and follow the instructions that are included with the kit.
TO INCREASE STATION HEIGHT MORE THAN 6 INCHES or TO REDUCE THE STATION HEIGHT:
REMOVE EXISTING COVER ASSEMBLY (Fig. 6)
If your existing station has a welded-on cover shroud you will need the
appropriate replacement cover kit (see Table 2, page 15).
1. Turn off all power to the grinder pump station.
2. Remove the tank lid and the electrical shroud.
3. Unplug the electrical quick disconnect (EQD) and remove the EQD
from the supply cable. Note: DO NOT CUT CABLE. Loosen liquid tight
cable connector and pull the supply cable out through the connector on
the side of tank.
4. Tape the pump breather cable to the vent pipe in the tank.
5. Remove the soil around the tank, exposing three of
the tank corrugations below grade. Use caution not to
damage buried cable.
6. Remove existing cover shroud.
6a. Welded-on shroud (standard) - Using a hand saw,
cut the tank in the valley between the two corrugations at
grade, discard existing welded-on shroud and attached
corrugations (shroud is not to be reused). Caution:
Be careful not to cut either the vent pipe or the pump
breather cable.
6b. Clamped-on shroud - Remove band clamp and
cover shroud.
Figure 6
Figure 7
REDUCING STATION HEIGHT (Fig. 7)
7. Using a hand saw, cut the tank in the valley
between the two corrugations at grade.
8. Cut vent pipe 4 ¾” above the cut made on the
tank. Proceed to step 16.
INCREASING STATION HEIGHT (Fig. 8 and Fig. 9)
9. Remove the soil around the tank exposing it
18” deeper than the extension being installed. For
example, if you have a 2’ extension (not including the
coupler) you must dig down 3’6” minimum from
grade; if you have a 4’ extension (not including the
coupler) you must dig down 5’6” minimum from
grade. Use caution not to damage buried cable.
10. Measure from grade down 2’ (for a 2’
extension) or 4’ (for a 4’ extension) and mark
accessway. Using a hand saw, cut the tank in the
valley between the two corrugations that are closest
to your mark. Note: Make sure the welded-on
shroud of the extension will be at grade level. Be
sure you are not cutting into the wet well and you
must have two corrugations below your cut, if there
are less than two corrugations, this extension kit can
not be used.
Caution: Be careful not to cut either the vent pipe
or the pump breather cable.

11. Attach the vent pipe extension with the 2” vent coupling, bringing the vent well above grade.
12. Clean all dirt and debris from top four corrugations on tank. Install the 24” coupler O-ring on the tank
between the top two corrugations with the white or yellow line facing out and on top.
13. Lube extension coupler and coupler O-ring with pipe lube or dish soap.
14. Manually press coupling evenly over lubricated O-ring. If additional force is needed, place a plywood
cover over the accessway and apply gentle mechanical pressure to the coupler. Note: Care must be used
when pushing down on the coupler. Excessive force or impact may result in damage and leakage.
15. Frequent visual inspections during installation must be performed to determine when the tank has fully
engage the coupler.
INSTALL REPLACEMENT COVER ASSEMBLY (Fig. 10)
16. Clean top corrugation on accessway extension and
mating surface of replacement shroud with acetone.
17. Liberally apply the silicone sealer provided to the
under side of the replacement shroud where it will come in
contact with the accessway extension.
18. Lube wet well vent grommet and vent pipe extension
with pipe lube, non-grit hand cleaner or dish soap and
slide vent pipe through grommet until tank shroud seats to
accessway.
19. Place SS band clamp around top corrugation and the
replacement shroud. Tap with a mallet around clamp to help
seat the clamp. Torque stud assembly on band clamp to a
maximum 125 inlb.
20. Reinstall the supply cable, EQD**, tank lid and
electrical shroud and tighten cable connector. (**See “EQD
wiring order,” Table 1)
21. Follow start-up procedures to ensure proper pump operation (you will

NOTE: IF EXISTING
ACCESSWAY HAS ONLY 2
CORRUGATIONS (Fig. 11)
- If the coupler will not
engage completely because the
discharge piping is in the way,
and it doesn’t have a cut out,
you will need to cut a slot in the
coupler.
- Using a hand, reciprocating
or hole saw, cut an arch in the
coupler; the cut-out is not to
exceed 5.50” tall or 5.00” wide.

User Instructions for the Environment One Grinder Pump
General Information
Your home is served by a low pressure sewer system; the key element is an Environment One grinder pump.
The tank collects all solid materials and wastewater from the house. The solid materials are then ground to a
small size suitable for pumping as a slurry with the wastewater. The grinder pump generates sufficient pressure
to pump this slurry from your home to the wastewater treatment receiving line and/or disposal plant.
This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: 1) this
device may not cause harmful interference; and 2) this device must accept any interference received, including
interference that may cause undesired operation. Any changes or modifications not expressly approved by the
party responsible for compliance could void the user’s authority to operate this equipment.
Care and Use of your Grinder Pump
The Environment One grinder pump is capable of accepting and pumping a wide range of materials, and an
extensive grind test is required in order to obtain NSF approval. However, regulatory agencies advise that the
following items should not be introduced into any sewer, either directly or through a kitchen waste disposal unit:
Glass
Seafood shells
Diapers, socks, rags or cloth
Syringes
Cotton swabs
Personal/cleaning wipes & sponges
Disposable toothbrushes
Latex/vinyl items
Metal
Plastic objects (toys, utensils, etc.)
Kitty litter
Dental floss
Aquarium gravel
Sanitary napkins or tampons
Cigarette butts
Caution: Kitchen garbage disposals do not keep grease/oil out of the plumbing system
In addition, you must never introduce into any sewer:
Explosives
Strong chemicals
Flammable material
Gasoline
Lubricating oil and/or grease
Items introduced into the sewer system from your home can potentially impact the water environment. Proper
disposal of household wastes such as window cleaners, unused/expired pharmaceuticals, paint thinners, fats,
fruit labels, etc. is important. For more information, visit http://www.wef.org.
Periods of Disuse
If your home or building is left unoccupied for longer than a couple of weeks, perform the following procedure:
Purge the System. Run clean water into the unit until the pump activates. Immediately turn off the water and
allow the grinder pump to run until it shuts off automatically.
Duplex Units. Special attention must be taken to ensure that both pumps turn on when clean water is added to
the tank.
Caution: Do not disconnect power to the unit
Power Failure
Your grinder pump cannot dispose of wastewater without electrical power. If electrical power service is
interrupted, keep water usage to a minimum.
Pump Failure Alarm
Your Environment One grinder pump has been manufactured to produce an alarm signal (120 volt) in the
event of a high water level in the basin. The installer must see that the alarm signal provided is connected
to an audible and/or visual alarm in such a manner as to
provide adequate warning to the user that service is required.
During the interim prior to the arrival of an authorized service
technician, water usage must be limited to the reserve
capacity of the tank.
For service, please call your local distributor:
